At the age of one, the dog's teeth grew, about 42. At the age of 2, the teeth began to scale, the mandibular incisors were gradually smoothed at the age of 3-6, the maxillary incisors were rounded at the age of 7, and gradually fell off after the age of 9.

Premature tooth loss in dogs is related to calcium deficiency and periodontal disease. At present, there is no special remedy. I suggest you take your dog to a regular animal hospital for a check-up and feed it some digestible soft food. If it is calcium deficiency after examination, you should take medicine. I suggest you choose less expensive calcium carbonate and calcium lactate, and at the same time inject vitamin D3, take vitamin D2 and vitamin D3 tablets orally. Of course, if conditions permit, you can also choose some imported brands of calcium for pets, because these products are still relatively professional.

I hope I can help you and take care of the dog.
